As you are undecided still, allow me to tell you a few of our features.
Many contests run in our guild, even occasionally multiple at once.
We also have a deck building guide, which was made by a person who can easily make the top 500 tournament place, and could probably make the top 150 if he tried.
We have a preset list, with both many budget (5k or below) decks and decks made by or favorites of our founder, who had, until recently, 1300 ELO.
Among our ranks are a few T2 players, so we can also help you if you wish to try out the oher game modes.
Once again, Engulfing Darkness would be glad to have you.
